A trio of researchers from Slovenia's Institute for the Protection of Cultural Heritage of Slovenia at the Centre for Preventive Archaeology and Eberhard Karls Universität Tübingen, in Germany, has found evidence of the oldest known use of cosmetics at a dig site in the Balkans. In their paper published in the Journal of Archaeological Science: Reports, Bine Kramberger, Christoph Berthold and Cynthianne Spiteri describe the ceramic bottles that held the cosmetics and what they found inside them.
